WebAs a side effect of this command the HyperLogLog internals may be updated to reflect a different estimation of the number of unique items added so far (the cardinality of the set). If the approximated cardinality estimated by the HyperLogLog changed after executing the command, PFADD returns 1, otherwise 0 is returned. WebRedis HyperLogLog: A Deep Dive Calculate vast sets at the speed of Redis Need to count millions of items at lightning speeds? Discover Redis HyperLogLog – a probabilistic data structure that enables you to approximate millions of values and elements in large sets with extreme space efficiency.
WebHyperLogLog in Redis Open source Redis implements HyperLogLog (HLL) as a native data-structure. It supports adding elements ( PFADD) to an HLL, counting elements ( PFCOUNT) of HLLs, and merging of ( PFMERGE) HLLs. Here is an example of a simple write case: Here is an example of a concurrent add case: The DEL-wins approach Web1 ago 2016 · PFADD returns 1 if the approximated cardinality of the HyperLogLog was changed when adding the element.
